Nos Astra is the capital city of the asari colony world Illium in the Crescent Nebula. The city includes a port, a bar, and a commercial area containing several shops. Though it seems like a gleaming, beautiful city outwardly, it is remarked by some characters that the city is not as safe as it looks and that it can be as dangerous as Omega. Illium has also been compared to Noveria because of its policies on trade.
